SHADE-SUPPORTING DEVICE.

Specification of Letters Patent.

Patented Jan. 14, 1913.

Application led March 1, 1912. Serial No. 680,791.

To all whom t may concern Be it known that I, BENJAMIN J. JAco- WAY, acitizen of the United States, residing at Memphis, in the county ofShelby and State of Tennessee, have invented new and useful Improvementsin Shade-Supporting 'tion is the provision of a simple and efficientdevice of this character wherein the operating mechanism for controllingthe movement of the shade may be placed at any desired point on theframe irrespective of the position of the shade supports.

A further object of this invention is the provision of a device of thischaracter which is so constructed that it may be used either inside theframe adjacent the sash or on the outside of the frame, as shown in thedrawin s.

(lnother object of the invention is to provide novel means for securingthe guide rods for the shade brackets and to construct these parts witha minimum amount of material and secure the guide rods therein withoutthe use of fastening devices, such as set screws, or the like.

Another, and one of the most important objects of the invention, is toprovide means whereby the tension of the spring in the shade roller maybe readily adjusted without removing the roller from the brackets.

Further objects of this invention will appear as the following specicdescription is read in connection with the accompanying drawing, whichforms a part of this application, and in which j Figure 1 is a frontelevation showing the device applied to a window frame and with theshade in raised position. Fig. 2 shows a side elevation. Fig. 3 is adetail vertical sectional view through the upper rod and one of thepulley holders. Fig. 4: is a perspective view of one of the upper rodand pulley holders with the rod and pulleys removed therefrom. Fig. 5 isa detail vertical sectional view on the line 5-5 of Fig. 3. Fig. 6 is adetail vertical sectional view through the automatic adjuster grip andthrough the lower rod holder. Fig. 7 is a plan view of the rod andpulley holder blank. Fig. 8 is a similar view of the automatic grip.Fig. 9 is a detail side elevation showing in dotted lines the positionof the spring shaft of the shade roller when the tension is beingadjusted.

Referring more particularly to the drawings, 1 represents the ordinarywindow frame in which the sashes 2 and 3 are mounted as is usual.Secured to the upper portion of the frame on either side thereof aresimilarly constructed rod supporting members 4: which are constructedfrom the blanks or plates shown at 5 in Fig. 7 and are bent up into theform shown in Fig. 4. Suitable ears 6 and 7 are struck up from the plateto receive a pulley shaft 8 upon which are journaled the rope pulleys 9to be hereinafter described. The plate is bent upon the line 10, Fig. 7,and then again upon the line 11, suitable lugs 12 being struck up fromthe,

last portion and having apertures 13 therein to receive the guiding rod14. When the rod is applied to the lugs or ears 12, they are arranged inparallel relation, as shown in dotted lines in Fig. 5 and aresubsequently bent to the position shown in full lines in said ligure soas to bind upon the rod and prevent its movement in either direction. Asshown in Fig. 1, one of the rods 14: is connected Jc hro'ugh a union 15to an extension 16, whose lower end is secured against movement ineither direction by a supporting member 17 which is similar to the union15 in that it has the rod receiving ears 18 but in this lat-terinstance, both are bent in the same direction to prevent any depressionof the extension 16, whose upward movement is prevented by its contactwith the upper point upon the frame, not necessarily forming acontinuation of the rod 14, is an automatic grip 19 which is constructedfrom the blank 20, shown in Fig. 8, and bent up into the form shown insection in Fig. 6. This blank consists of the ears 21 which are bentfrom the body so as to lie in parallel relation and are apertured toreceive the pulley shaft 22, upon which the cable pulley 23 isjournaled. Projecting at right angles from the ears 21 are ears 24 and25, the former being provided with a rod receiving aperture 26 ofsomewhat larger diameter than the rod, and the latter being providedwith a notch 27 of a similar size to and adapted to receive the rod. Theears 24 and 25 are bent slightly beyond the parallel so that theyconverge.

`Passing over the Apulley 23 and having one of its free ends secured tothe union 15 in any suit-able manner is an operating cable 28, whoseopposite free end is connected through a union 29 to the looped ends ofan operating cord 30, one leg of which is passed over the inner pulley 9and down to its connection with the shade roller bracket 31. Theopposite leg of this cord is carried over the outer pulley 9 and acrosst-he upper portion of the frame to the outer pulley 9 of the oppositerod supporting bracket and down to connection with the shade supportingbracket 32. These shade supporting brackets are constructed of plates 33having longitudinally extending parallel ears 34 which are coiled intobearings which surround the rods 14 and are guided thereon. The shaderoller which is shown at 35 is provided with a headed stud at one endindicated at 36, which is preferably screwed intovthe end of the rollerin the form of an ordinary screw and which takes the place of the usualpintle on one end of the roller. A t the opposite end of the roller, thesquared spring shaft which is shown at 37 project-s through the bracketand is provided with the washer 38 and a cotter key 39 to preventdisplacement of the shaft in the bracket and also to prevent the bracketfrom swinging upon the rod. The brackets 31 and 32 are both identical inform, that is, each has a circular aperture 40 and a tangential slot 41.The bracket 31 is, however, in reversed position upon the rod, or inother words, the slot 41 is projected above the circular aperture 40while in the bracket 32, the slot is projected below the aperture,

` thus, by producing the bracket in this manner, there is only one dierequired to form both. By raising the squared shaft of the roller intothe circular aperture 40 of the bracket32, the entire roller may berotated thus if the curtain is unwound and the shaft forced into thecircular aperture 40 and the curtain wound up and the shaft againdropped into the slot 41. It will be seen that the tension of the springwill be increased upon the next operation of the shade. By reversingthis operation, the tension, of course, may be decreased.

It will be readily understood that when the automatic grip is released,that the weight of the shade upon the cables will raise the outer end ofthe automatic grip so as to cause the walls of the aperture 26 to bindupon the extension rod 16 and lock the automatic against upwardmovement. By depressing the outer or pulley end of the automatic gripuntil the ear 25 engages the rod, the automatic grip may be moved up ordown, as desired, so as to adjust the position of the shade on the rods14. The brackets 4 and the supporting unions 15 limit the upward ordownward movement of the shade brackets, while the unions 15 and thesupporting member 17 limit t-he upward or downward movement of theautomatic grip, as will be readily understood.
